The protagonist ァッコちゃん is a young girl who can change into anything through the mirror. At first, she was set as a big mirror, and she could transform herself by saying a spell in the mirror. Later, she was changed into a portable, shell-shaped deformation box.
In the story setting of the animated version, the three works are different. In addition to the painting style, the shapes of ァッコちゃん clothes and deformation boxes are also different from their parents' occupations.
